Why Do Planes Feel So Cold? The Science Behind Airplane Cabin Temperatures

Have you ever boarded a plane, bundled up in warm clothes, only to find yourself shivering despite your best efforts? You're not alone. The cool temperature inside airplane cabins is a deliberate choice, and there are some compelling scientific reasons behind it. Let's explore why airlines keep things chilly.

Benefits of a Cool Cabin Temperature

Preventing Fainting: The air pressure at high altitudes is significantly lower than on the ground, and the combination of thin air and excessive heat can lead to passengers feeling faint. A cooler cabin helps maintain a stable body temperature, preventing this discomfort.

Reducing Dehydration: Airplane cabins have very dry air, and this dryness can lead to dehydration. A lower temperature slows down the evaporation of bodily fluids, making it easier to stay hydrated.

Minimizing Odors: Warmer temperatures can amplify unpleasant smells, whether from food or other passengers. A cool cabin helps reduce the intensity of these odors, creating a more pleasant atmosphere.

Improving Air Quality: Keeping the cabin temperature cooler can help prevent the growth of bacteria and other microorganisms in the air, leading to improved air quality and a healthier environment for passengers.

How Cabin Temperature is Controlled

An airplane's temperature control system operates using multiple zones, each with its own specific temperature setting. The pilot has primary control over the overall cabin temperature, while the cabin crew can make minor adjustments as needed using their cabin controls.

Why is the cabin temperature on airplanes intentionally kept cool?

The cool temperature inside airplane cabins is intentional to prevent fainting due to the thin air at high altitudes. It also helps to reduce dehydration, minimize odors, and improve air quality.

How does a cool cabin temperature help reduce dehydration on flights?

A lower cabin temperature slows down the evaporation of bodily fluids, helping to combat dehydration caused by the dry air on airplanes.

How do airplane cabin temperature control systems work?

The temperature control system on an airplane uses multiple zones, each with its own temperature setting. The pilot has primary control, while cabin crew can make minor adjustments using their cabin controls.

What are some ways to stay comfortable in a cool airplane cabin?

It's always a good idea to be prepared with warm clothing when traveling. Pack a sweater, scarf, or light jacket to combat the cool cabin temperature, regardless of the weather at your destination.

Be Prepared for the Cool

While airlines strive to maintain comfortable temperatures, it's always a good idea to be prepared. Pack a sweater, scarf, or light jacket to combat the cool cabin temperature, regardless of the weather at your destination. Staying warm will ensure a more enjoyable and comfortable travel experience.
